Experimental probability
Ian Bailey-Mortimer
Guided Notes
Key concepts students will learn:
- •
Experimental probability is found by calculating the relative frequency of an event based on actual experimental outcomes.
- •
To find the experimental probability, divide the number of times an outcome occurs by the total number of trials.
- •
The expected frequency can be predicted by multiplying the experimental probability by a new number of trials.

“A spinner has 5 equally sized sections numbered 1 to 5. You spin the spinner 30 times and record the number it lands on each time. The results are: 1 (8 times), 2 (5 times), 3 (6 times), 4 (7 times), 5 (4 times). What is the experimental probability of spinning a 4?”
